Yeah, that was it. Are you still getting the "detecting threats are being cleaned" message? If so, its coming from windows defender. I would highly recommend downloading a free antivirus program such as Avast or bitdefender. If you install Avast make sure you do a custom install and only choose to install the web shield, file shield, behavior shield and if you use a third party program to download your email then also choose the email shield, uncheck everything else.
